Without testing the extension it is difficult to say.
Which extension builder did you use, or is it not your extension ? If not yours have you asked the extension developer for help ?
This is my extension. It measures internet speed. If I give it to you, I'll fix the compilation error and post it in the community for free.
The extension works well in the emulator.
I use FAST-CLI to compile the extension.

You can share your aia project by private message if you wish.
You could also share your .java file from your extension, so I can see if there are any issues there...

Just to follow this up, I got a couple of errors in the @DesignerComponent stanza when running the java in Intellij. Removed these, built the extension and this then compiled the apk.

Did you delete the component's "appearance" settings in the designer menu (category, visibility, and icon) and that's it? Did that solve the error? I only found this difference by comparing the old code with yours.

Yes. The first one category is deprecated
TIMAI2:
I edited the Designer Component stanza from this:
@DesignerComponent(
version = 23, // ΠΠΎΠ΄Π½ΡΠ»ΠΈ Π²Π΅ΡΡΠΈΡ, ΡΡΠΎΠ±Ρ ΡΠ±ΡΠΎΡΠΈΡΡ ΠΊΡΡ Kodular
description = "ΠΡΠΎΠ΄Π²ΠΈΠ½ΡΡΡΠΉ ΠΈΠ·ΠΌΠ΅ΡΠΈΡΠ΅Π»Ρ ΡΠΊΠΎΡΠΎΡΡΠΈ ΠΈΠ½ΡΠ΅ΡΠ½Π΅ΡΠ° Ρ ΠΏΠΎΠ»Π½ΠΎΠΉ ΠΊΠ°ΡΡΠΎΠΌΠΈΠ·Π°ΡΠΈΠ΅ΠΉ.",
category = ComponentCategory.EXTENSION,
nonVisible = true,
)
to this:
@DesignerComponent(
version = 25, // ΠΠΎΠ΄Π½ΡΠ»ΠΈ Π²Π΅ΡΡΠΈΡ, ΡΡΠΎΠ±Ρ ΡΠ±ΡΠΎΡΠΈΡΡ ΠΊΡΡ Kodular
description = "ΠΡΠΎΠ΄Π²ΠΈΠ½ΡΡΡΠΉ ΠΈΠ·ΠΌΠ΅ΡΠΈΡΠ΅Π»Ρ ΡΠΊΠΎΡΠΎΡΡΠΈ ΠΈΠ½ΡΠ΅ΡΠ½Π΅ΡΠ° Ρ ΠΏΠΎΠ»Π½ΠΎΠΉ ΠΊΠ°ΡΡΠΎΠΌΠΈΠ·Π°ΡΠΈΠ΅ΠΉ."

The last two items were showing problems in intellij...
